Manufacturing method and manufacturing apparatus for filling material having twisted portion

Technical field

The present invention relates to a manufacturing method and a manufacturing apparatus for a filler having a twisted portion.

Background art

[0002] At present, the method of filling edible into a cylindrical edible casing such as a collagen casing is widely used in foods such as sausages and cheeses, as well as animal foods in zoos, It is known to be used as feed for cultured fish such as gusset. Among these, sausage and cheese are manufactured continuously and at high speed in a short time using a known manufacturing apparatus.

[0003] As an example of a sausage manufacturing apparatus, there is an apparatus known from Japanese Patent Publication No. 40-27509. According to this apparatus, sausages that are filled caustic connected through twisted parts are produced in a chain. The chained sausages are cooked in a smoke house, then cut at the twist and separated individually. Collagen casings are not heat welded even when heat-treated in a smoke house. Therefore, the casings at both ends separated individually are twisted back. However, since the sausage raw material filled in the casing is hardened by heat denaturation, the force of the casing where the sausage raw material has been twisted does not leak.

[0004] On the other hand, when food for animals at zoos or food for cultured fish such as tuna and gusset is heated, the nutritional components, flavor and texture change after heating. Do not apply. For this purpose, the casings at both ends must be closed so that the feed ingredients do not leak from the casings at both ends of the individually separated feed.

[0005] As a method for producing the above-mentioned feed, a method disclosed in Japanese Patent Application Laid-Open No. 2004-65167 is known. According to this manufacturing method, for each filling, the casing is twisted at least four times to form a bait material filling part and a link part, and each link part is crimped, fused by heating, or tied by string, tape or thread. Block. Further, the above publication discloses a method of applying a gelatin to a twisted link portion and bonding the link portion. However, In any of the methods, after forming the twisted portion, it is necessary to separately perform a ligation process of the twisted portion, and therefore, continuous and high-speed production of feed is impossible.

[0006] In this way, the continuous and high-speed link portion closing method capable of preventing the twisting-back generated in the twisted portions of the individually separated packings was effective, so that the filling with fluid contents was possible. It was not possible to commercialize food products, for example, food for use without heating.

With such a configuration, it is possible to bond the twisted portion with an inner force.

[0015] In the second invention, at least a part of the outer periphery of the twisted portion can be covered with at least a part of the adhesive applied to the outer periphery of the filled casing. With such a configuration, the twisted portion can be bonded from the outside.

[0016] In the second invention, the adhesive application nozzle may continuously discharge the adhesive. Such a configuration makes it easy and easy to apply the adhesive to the outer periphery of the filled casing.

[0017] In the second invention, the adhesive application nozzle can discharge the adhesive intermittently. With such a configuration, the amount of adhesive to be applied can be reduced, and a filler in which the adhesive is applied only to the twisted portion can be manufactured. [0018] In the first and second inventions, a filling having a twisted portion that does not cause twisting-back, for example, a non-heated product having a flowable content can be manufactured continuously and at high speed. .

In the first and second aspects of the invention, since the inner portion can be bonded to the twisted portion, the bonding strength of the twisted portion can be increased.

In the first and second inventions, since the outer portion can be bonded to the twisted portion, the bonding strength of the twisted portion can be increased.

[0019] In particular, in the second invention, since the adhesive applicator can have a simple structure, the manufacturing cost can be further reduced.

However, a casing (human escaping, natural intestine casing) that is not actually limited to this example, and Any material can be used as long as it has the original function. Any product can be used as long as the product is filled in the casing and has twisted parts at both ends. It's okay! [0023] In the following, a manufacturing method and a manufacturing apparatus for a filling material having a twisted portion such as bait for large-scale cultured fish such as tuna and yellowtail, or animal food at a zoo or the like will be described. Reference numeral 1 denotes a filler manufacturing apparatus having the twisted portion of the present invention installed on the floor surface FL. Reference numeral 2 is a main body housing, and reference numeral 3 is a filling tube. The filling tube 3 is a cylindrical member having an inlet 3a for feeding the feed as content on the front side and a discharge outlet 3b for the content at the tip. The inlet 3a supplies the content during filling. Communicating with pump 4

[0024] An edible casing 5 is fitted into the filling tube 3 from a discharge port 3b at the tip thereof. The casing 5 is formed of collagen or carrageenan.

Reference numeral 6 denotes a filling casing rotating means for rotating the filling casing 7 filled with the contents in the casing 5. In this example, the filling tube 3 and the braking member 8 with which the tip of the filling tube 3 is fitted at the time of filling constitute the filling casing rotating means 6. However, the filling casing rotating means 6 differs depending on the material of the casing 5 each time. For example, collagen casing and cellulose casing are rotationally driven by the rotation of the braking member 8 so that the driving by the filling tube 3 is not essential, and the natural intestine casing is rotationally driven by the rotation of the filling tube 3 and the braking member 8 is driven. Is not required.

[0026] The main body housing 2 has the pump 4, the filling pipe reciprocating drive means 9 for moving the filling pipe 3 forward and backward with respect to the braking member 8, and the filling for rotationally driving the filling pipe 3 A tube rotation drive housing 10, a brake member rotation drive housing 11 for rotationally driving the brake member 8, a link formation means 12 having a pincher member 13 for restricting the filling casing 7, and a link formation for driving the link formation means 12 Adhesive application means 20 having an adhesive application nozzle 22 for applying an adhesive 21 to the outer periphery 7A of the means motor 12M and the filling casing 7 is mounted at predetermined positions.

The brake member 8 is rotatably supported by a brake member rotation drive housing 11 as shown in FIG. The braking member 8 reliably transmits the rotation to the filling casing 7.

[0028] The filling pipe reciprocating drive means 9 reciprocates the filling pipe 3 supported by the filling housing 4A between the standby position shown in FIG. 1 and the filling operation position shown in FIG. The position of the filling tube 3 shown in FIG. 2 is a position where the contents are filled into the casing 5 from the discharge port 3b at the tip of the filling tube 3. [0029] The filling tube rotation drive housing 10 rotationally drives the filling tube 3 at the position shown in FIG. The filling tube 3 rotates in synchronization with the braking member 8.

[0030] As shown in FIG. 7, the link forming means 12 has a filling casing moving means 15 for moving the filling casing 7 narrowed by the pincher members 13, 13 toward the rear (arrow A direction). ing. The pincher members 13 and 13 are located at a predetermined distance C from the discharge port 3b of the filling tube 3 at the rear I (content discharge direction, arrow A direction), that is, around the rotary shaft 14 disposed on the throttle position I in the arrow D direction. And the stuffed casing 7 is squeezed on the squeezed position I to form the squeezed portion 7a-1.

As shown in FIG. 3, the pincher member 13 is formed with a V-shaped portion, and when the maximum narrowing is achieved in which the filling casing 7 is squeezed by a pair of left and right pincher members 13 and 13, as shown in FIG. The pincher members 13 are disposed so as to have a gap with the outer periphery 7aa of the twisted portion 7a formed between the pincher members 13 and 13.

[0032] As shown in FIGS. 2 and 7, the filling casing moving means 15 includes a pair of left and right endless chains 15a, 15a to which a pincher member 13 is attached. A plurality of pincher members 13 are attached to the chain 15a at equal intervals with an interval E. Between the pincher members 13 and 13, a filling material is manufactured in which the total of the twisted portion 7 a and the filling portion 7 b is the same as the distance E. The chain 15a is stretched between a drive sprocket 15b fixed to the rotary shaft 14 and an idler 15c, and circulates in the direction of arrow D. The filling casing moving means 15 may be a belt and a pulley.

[0033] A lug 15d is attached to the chain 15a. As shown in Fig. 3 (B) and Fig. 3 (C), the lug 15d engages with the outer periphery 7A of the filling casing 7 to prevent rotational shaking of the filling casing 7, and the outer periphery 7A of the filling casing 7 and the adhesive application nozzle Maintain the distance F from 22. Further, the lug 15d comes into contact with the adhesive 21 applied to the outer periphery 7A of the rotating filling casing 7, and extends a part of the adhesive 21 along the circumferential direction G of the outer periphery 7A. In consideration of these, a desired number of lugs 15d in which recesses 15dd having a desired shape are formed are arranged at desired positions between the pincher members 13 and 13.

[0034] Referring to FIGS. 1 and 4, the adhesive application means 20 adheres to the outer periphery 7A of the filled casing 7. Adhesive application nozzle 22 which is a cylindrical member for applying adhesive 21, adhesive discharge valve body 23 which is mounted on braking member rotating drive housing 11 and has adhesive application nozzle 22 fixed thereto, and main body nozzle Adhesive pump 25, which is placed on uzing 2 and pumps adhesive 21 to adhesive discharge nozzle body 23 via conduit 24, and adhesive which stores adhesive 21 in communication with adhesive pump 25 A tank 26 and an air solenoid valve 27 for supplying driving air from the air source 28 to the adhesive discharge valve body 23 are provided.

[0035] Adhesive 21 is gelatin heated to 80 ° C and melted. Gelatin is edible and can produce bait for large-scale farmed fish such as tuna and gusset, and animal food at zoos without any problems.

. Of course, non-edible adhesives may be used when producing fillings other than food and food.

The adhesive application nozzle 22 is positioned above the filling casing 7 with a distance F. The adhesive application nozzle 22 forms a link with the discharge port 3b of the filling tube 3 at a predetermined distance H from the discharge port 3b of the filling tube 3 at the position shown in FIG. Arranged at position II between the rotating shafts 14 of the means 12. The adhesive application nozzle 22 on the position II is located in front of the locus circles Q and Q around the rotation axis 14 of the top portion 13a of the pair of pincher members 13 and 13 and behind the end portion 8a of the braking member 8. Therefore, the adhesive 21 discharged from the adhesive application nozzle 22 can be applied to the location 7a-2 where a twisted portion to be described later is formed.

[0037] Referring to FIGS. 3 and 6, the adhesive 21 discharged from the adhesive application nozzle 22 is an application portion having a predetermined width 21a and a predetermined thickness 2 lb on the outer periphery 7A of the filling case 7. 21 A forms. The width 21a and the thickness 21b of the application part 21A are variable according to the diameter d of the adhesive application nozzle 22 and the discharge pressure of the adhesive 21. Also, the application portion 21A having a large width 21a can be formed by making the opening of the adhesive application nozzle 22 rectangular or elliptical.

The adhesive discharge valve body 23, the conduit 24, the adhesive pump 25, and the adhesive tank 26 are temperature controlled so that the gelatin as the adhesive 21 maintains a predetermined temperature.

[0038] The adhesive application unit 20 further includes an adhesive discharge control unit 29 for intermittently applying the adhesive 21 to the filled casing 7. Referring to FIGS. 1 and 4, reference numeral 29A is a detecting means for detecting the amount of rotation of the rotating shaft 14 of the link forming means 12, that is, the amount of movement of the pincher member 13. The detection means 29A is a motor of a rotating shaft 14 and a link forming means motor 12M. A toothed disk 29A1 fixed to a shaft 14A connected to the shaft and a sensor 29A2 for detecting the tooth portion of the toothed disk 29A1 are provided. Reference numeral 29B is a programmable controller that outputs a signal S2 for actuating the air solenoid valve 27 based on the detection signal S1 of the detection means 29A. The programmable controller 29B also outputs a signal S3 for controlling the operation of the link forming means motor 12M.

[0039] Referring to FIG. 7, programmable controller 29B stops link forming means motor 12M so that pincher member 13 stops at original position III when the filling of one casing 5 is completed. Then, the pincher member 13 outputs a signal in which the distance between the original position III and the adhesive discharge start position IV is moved, and the pincher member 13 outputs the adhesive discharge start position IV and the adhesive discharge end. It is configured to output a signal that moves the distance between positions V.

[0040] Referring to FIG. 4, the solenoid valve 27 for air is opened by the signal S2 from the programmable controller 29B, and the adhesive discharge valve 23A provided in the adhesive discharge valve body 23 is opened by the drive air. Then, the adhesive 21 is discharged from the adhesive application nozzle 22 toward the filling casing 7. The discharged adhesive 21 is applied to the portion 7a-2 where the twisted portion 7a on the outer periphery 7A of the filled casing 7 is formed. Thereafter, the air solenoid valve 27 is closed by the signal S2 from the programmable controller 29B, and the discharge of the adhesive from the adhesive application nozzle 22 is completed.

[0041] Next, a method of manufacturing the chain-like filler 70 connected by the twisted portion 7a as shown in Fig. 5 will be described.

[0042] The filling tube 3 at the position shown in FIG. 1 is moved toward the braking member 8. The filling tube 3 moves to the filling work position shown in FIG. 2 in a state of being fitted to the casing 5 held at a predetermined position. The casing 5 on the filling tube 3 engages with the braking member 8. The pump 4 is driven and at the same time the link forming means 12 is driven. The link forming means 12 moves the formed filling casing 7 backward.

The contents supplied from the pump 4 into the filling tube 3 are discharged from the discharge port 3 b at the tip of the filling tube 3 and filled into the casing 5. The filled casing 7 moves in the rear A direction while being constricted by a pair of left and right pincher members 13, 13 of the link forming means 12. [0044] Referring to Figs. 4 to 9 and 10, after adhesive 21 is applied linearly only to the portion 7a-2 where the twisted portion 7a is formed, the adhesive 21 is applied only to the twisted portion 7a. A method for producing the coated filler will be described.

In the apparatus of FIG. 4, the adhesive 21 is intermittently discharged from the adhesive application nozzle 22.

In this apparatus, when the application of the adhesive 21 to the filling casing 7 is completed, the filling tube 3 and the braking member 8 are rotated in the direction of arrow R to form the twisted portion 7a starting from the throttle portion 7a-1.

FIG. 4 shows the state of the adhesive 21 (adhesive application portion 21 A) applied to the location 7a-2 that becomes the twisted portion 7a. The adhesive 21 is applied in a straight line because the filling casing 7 is not rotated. Thereafter, the rearmost end side of the application portion 21A is narrowed by a pair of left and right pincher members 13 (see FIG. 7).

[0047] When the rearmost end side to which the adhesive 21 is applied is constricted by the pair of left and right pincher members 13, the filling casing 7 is rotated, so that the portion to which the adhesive 21 is applied is twisted five times. A twisted portion 7a is formed at the location. At that time, the adhesive 21 is spirally wound into the twisted portion 7a and adheres the twisted portion 7a from the inside.

[0048] The operation of spirally winding the adhesive 21 into the twisted portion 7a will be described in detail with reference to Figs. The link forming means 12 is continuously rotated at a predetermined speed. Then, the interval between the pincher members 13 is set so that the filling length of the filling casing 7 is 108 mm and the filling diameter is 30 mm, and the number of twists is set to five. When the number of twists is 5, the twisted part length is 25 mm, the twisted part diameter is 5 mm, and the product length is 133 mm as shown in Fig. 5.

[0049] As shown in Fig. 6, the spiral with a twisted part length of 25mm (right figure) is solved, and the length becomes 35mm (left figure). That is, in order to form the twisted portion 7a, the filling casing 7 needs 35 mm. In order for the adhesive 21 to be caught in the twisted portion 7a, it is only necessary to apply the adhesive 21 in a range of 35 mm to both ends of the filled casing 7 with a filling length of 108 mm.

[0050] This will be described with reference to FIG. The pincher member 13 provided in the link forming means 12 that continuously rotates at a predetermined speed, and when the pincher member 13 that newly squeezes the filling casing 7 reaches the adhesive discharge start position IV that is the predetermined position, the adhesive agent Connected from application nozzle 22 The adhesive 21 is discharged, and the adhesive 21 is started to be applied to the outer periphery 7A of the filling casing 7 which is not rotating. Since the filling casing 7 is not rotating, it is difficult for the adhesive dripping position to shift. The distance F between the filling casing 7 and the adhesive application nozzle 22 can be increased.

[0051] When the pincher member 13 reaches the adhesive discharge end position V which is a predetermined position, the adhesive application nozzle 22 ends the discharge of the adhesive 21. A linear adhesive application part 21A is formed on the outer periphery 7A of the casing 7 at the same pitch as the pincher interval E with a product length of 133mm. In this case, the distance between the adhesive discharge start position IV and the adhesive discharge end position V, which is the moving distance of the pincher member 13, corresponds to the adhesive application portion length K, that is, 35 mm.

[0052] The distance between the position II of the adhesive application nozzle 22 and the throttle position I, that is, the distance that the adhesive application part 21A moves is the distance between the pinch member 13 between the adhesive discharge start position IV and the throttle position I. Equal to distance. For this reason, the adhesive application portion 21A and the pincher member 13 reach the drawing position I at the same time, and the pincher member 13 squeezes the rearmost end side of the adhesive application portion 21A to form the drawing portion 7a-1. The

[0053] When application of the adhesive 21 is completed, the filling tube 3 and the braking member 8 start to rotate, and the filling casing 7 is rotated. Subsequently, since the narrowed portion 7a-1 is formed as described above, the formation of the twisted portion 7a is started on the front (arrow B direction) side with the narrowed portion 7a-1 as a starting point. While the adhesive application nozzle 22 is not discharging the adhesive 21, the filled casing 7 rotates at a rotational speed that gives five twists to the twisted portion 7 a.

[0054] The adhesive application portion length K is set equal to the length of the casing used to form the twisted portion 7a, for example, the casing length 35mm used for twisting 5 times. Only applied to twisted part 7a. It should be noted that the adhesive application portion length K may be longer than the length of the filled casing 7 used for forming the twisted portion 7a, or may be shorter as long as the twisted portion 7a does not return. The number of twists is not limited to five. For example, it may be 3 times or 7 times.

[0055] Next, the operation of winding the adhesive 21 applied to the outer periphery 7A of the filled casing 7 into the twisted portion 7a will be described below.

Referring to FIG. 8, when pincher member 13 squeezes filling casing 7 at squeezing position I, squeezing is performed. A large number of pleats 7C are generated in the casing 7a-1 and end 7B, and the adhesive 21 applied to the outer periphery 7A of the filled casing 7 is applied to the pleat 7C and pleat 7A-1 and end 7B. 7 Interspersed between C.

[0057] Referring to FIG. 9 and FIG. 10, when the throttle portion 7a-1 begins to twist based on the rotation of the filling casing 7, the above-mentioned numerous (for example, 20) pleats 7C of the throttle portion 7a-l Each folds in the direction of rotation (in the direction of arrow R) and begins to fold with adhesive 21 on each fold 7C adjacent to each fold 7C. The folds 7C and the pleats 7C, which have been folded to start forming the twisted portion 7a, face each other in an adhesive state. By twisting the throttle 7a-1 in this way, the adhesive 21 interposed between the pleat 7C and the pleat 7C of the throttle 7a-1 is folded into the fold 7C and the fold 7C inside the twist 7a. (Fig. 10 (A)).

Referring to FIGS. 9 and 10, in this example, filling casing 7 rotates five times, and the casing of end portion 7B of filling casing 7 is squeezed while being twisted based on the rotation. Then, the length of the twisted portion 7a is increased as the twisted portion 7a is sequentially converted. In the process, the fold 7C of the end 7B is also squeezed while being folded in the direction of rotation (arrow R direction), and each fold 7C adjacent to each of the folds 7C is the same as the fold 7C of the throttle 7a-1 Folded with adhesive 21 on top.

[0059] In this apparatus, as described above, the adhesive 21 applied to the outer periphery 7A of the filled casing 7 is wound into the twisted portion 7a.

[0060] Depending on the amount of the adhesive 21 interposed between the pleats 7C, the size of the pleats 7C, the strength of twisting, and the like, the adhesive 21 squeezes the pleat 7C force in the process of forming the twisted portion 7a. The adhesive 21 shown in (B) of FIG. 9 and (B) of FIG. 10 applies the outer circumference 7aa of the twisted portion 7a along the spiral adhesive portion 21 formed inside the twisted portion 7a. The covered adhesive is shown. This adhesive 21 bonds the twisted portion 7a from the outside.

Next, referring to FIGS. 7 and 10 (C) and (D), an amount of adhesive 21 that cannot fit between the pleats 7 C and 7 C is applied to the outer periphery 7 A of the filled casing 7. An example of applying a filler by applying V will be explained. The adhesive 21 adhered to the outer periphery of the pleat 7C generated by being squeezed at the squeezing position I is rotated along with the rotation of the filling casing 7, and extends and adheres to the outer periphery 7aa of the twisted portion 7a in the circumferential direction (arrow G direction). This adhesive 21 covers the outer periphery 7aa of the twisted portion 7a, so that the twisted portion 7a Glue a.

[0062] As shown in Figs. 10 and 11, the application state of the adhesive 21 to the twisted portion 7a formed by the above-described method, that is, the attached state, can be roughly as follows.

[0063] Fig. 10 shows the state of adhesion of the adhesive 21 in the outer peripheral direction (arrow G direction) of the twisted portion 7a.

(A) of FIG. 10 shows a crinkled state where the adhesive 21 inside the twisted portion 7a is hardly squeezed out and almost adheres to the outer periphery 7aa of the twisted portion 7a.

FIG. 10B shows a state where the adhesive 21 inside the twisted portion 7a is squeezed out and attached to the outer periphery 7aa of the twisted portion 7a.

(C) of FIG. 10 shows a state where the adhesive 21 that has been forced into the inside of the twisted portion 7a is unevenly distributed and adhered to the outer periphery 7aa of the twisted portion 7a.

(D) of FIG. 10 shows a state where the adhesive 21 that could not enter the inside of the twisted portion 7a adheres to almost the entire outer periphery 7aa of the twisted portion 7a.

[0064] Fig. 11 shows the state of adhesion of the adhesive 21 in the longitudinal direction (arrow L direction) of the twisted portion 7a.

(A) in FIG. 11 shows a crinkled state where the adhesive 21 inside the twisted portion 7a is hardly squeezed out and almost adheres to the outer periphery 7aa of the twisted portion 7a.

FIG. 11B shows a state where the adhesive 21 inside the twisted portion 7a is squeezed out and attached to the outer periphery 7aa of the twisted portion 7a.

(C) of FIG. 11 shows a state where the adhesive 21 that has been forced into the inside of the twisted portion 7a is unevenly distributed and adhered to the outer periphery 7aa of the twisted portion 7a.

(D) of FIG. 11 shows a state where the adhesive 21 that has been forced into the inside of the twisted portion 7a adheres to almost the entire outer periphery 7aa of the twisted portion 7a.

Next, referring to FIG. 12 and FIG. 13, the adhesive 21 is spirally applied only to the portion 7a-2 where the twisted portion 7a is formed, and then the adhesive 21 is applied only to the twisted portion 7a. The method for producing the applied filler will be described.

[0066] The filling tube 3 and the braking member 8 are always rotated continuously. Adhesive 21 is adhesive application nozzle 22 Force Twist 7a where 7a-2 is formed is the same length as in the above example shown in FIG.

That is, it is discharged over 35 mm. A spiral adhesive application portion 21A is formed on the outer periphery 7A of the filled casing 7 that is moving at a predetermined speed while continuously rotating at a predetermined rotation speed. [0067] In this example, the spiral pitch is about 29 mm. For this purpose, as shown in the figure, the spiral adhesive application portion 21A is formed 1.25 times at the location 7a-2. The helical pitch is determined by the length of the packing (distance E) and the number of twists of the twisted part 7a.

[0068] This example also exhibits substantially the same operation as the above-described example. That is, when the pincher members 13 and 13 reach the throttle position I shown in FIG. 7, as shown in FIG. 13, the filled casing 7 is squeezed by the pincher member 13 to form the throttle portion 7a-1. On the other hand, since the filled casing 7 always rotates continuously, the formed throttle portion 7a-1 has already begun to twist. The rotating filling casing 7 further twists the throttle portion 7a-1 to form a twisted portion 7a. The adhesive 21 is continuously applied in a spiral manner inside the twisted portion 7a to form an adhesive surface. Also in this example, the outer periphery 7aa of the twisted portion 7a is bonded to the adhesive 21 in substantially the same manner as shown in FIGS. 9B, 10B, 10D, and 11B. It can be covered with.

[0069] In this example, the adhesive application portion 21A is formed in a spiral shape, and the application length of the adhesive 21 is longer than that in the above-described example, so that the adhesive force is increased accordingly.

[0070] In the two manufacturing methods described above, the force used to manufacture the filling material in which the adhesive 21 is applied only to the twisted portion 7a. Next, referring to FIG. 14 and FIG. 15, the adhesive 21 is twisted. A method for producing a filling material applied to the part 7a and the filling part 7b will be described.

[0071] The filling pipe 3 and the braking member 8 are continuously rotated continuously. The adhesive 21 is continuously and continuously discharged from the adhesive application nozzle 22. As shown in FIG. 14, the adhesive 21 is spirally applied to the outer periphery 7A of the filled casing 7 at a pitch of about 29 mm similar to that shown in FIG. In this example, the adhesive 21 is spirally applied over the entire length of the filling portion 7b. However, because the adhesive is edible, there is no problem even if it is eaten by farmed fish or animals. In this example, since the adhesive discharge control means 29 is not necessary, the apparatus is simple.

[0072] This example also has substantially the same effect as the above-described example in which the filling tube 3 and the braking member 8 are always continuously rotated. That is, the end portion 7B of the filling casing 7 rotating in the direction of the arrow R is sequentially twisted and squeezed to increase the length of the twisted portion 7a, and the adhesive surface that is spirally connected in the twisted portion 7a ( Application part) is formed. Also in this example, the outer periphery 7aa of the twisted portion 7a can be covered with the adhesive 21.

Next, the packing separator 30 shown in FIG. 1 will be described. The packing separator 30 This is for separating the filler 70 connected by the twisted part 7a manufactured by the filler manufacturing apparatus 1 into individual fillers 70A. The filler separator 30 moves the filler 70 at the same speed as the link forming means 12 # 1 conveyor 31 and # 2 conveyor 32, and between the # 1 conveyor 31 and # 2 conveyor 32, the twisting section And a cutting blade 33 for cutting 7a. The cutting blade 33 is driven in synchronism with the link forming means 12 so as to cut the central portion of the twisted portion 7a.

[0074] In the individually separated filling 70A, the twisted portion 7a is coated with the adhesive 21, so that the twisted portion 7a is not twisted back. As a result, fluid contents will not leak from the twisted portion 7a.

[0075] The packing separator 30 is not limited to this example. For example, the separated packing 70A can be manufactured by using the link forming apparatus disclosed in Japanese Patent Laid-Open No. 2001-54352. This known device forms a twisted portion 7a, and cuts the twisted portion 7a immediately after forming the twisted portion 7a.

FIG. 16 and FIG. 17 show a filling production apparatus 40 having another twisted portion. This device 40 is provided with a filling pipe 3 having a discharge port 3b for discharging the contents into the casing 5, and a rear side (content discharge direction, arrow A direction) from the discharge port 3b, and the outer periphery of the filling casing 7 Adhesive application nozzle 22 for applying adhesive 21 to 7A, filling casing rotating means 6 for rotating filling casing 7 having filling pipe 3 and braking member 8 to which adhesive 21 has been applied, and adhesive application nozzle A pair of left and right rotating shafts 43, 43 provided rearward (in the content discharge direction) from 22 and a pair of left and right pincher members 42, 42 that rotate around the rotating shafts 43, 43 to squeeze the filling casing 7, A filling casing moving means 44 for moving the filling casing 7 rearward having a pair of rotation shafts (rotation drive shafts) 45, 45 provided at a predetermined distance M rearward (content discharge direction) from the rotation shaft 43. The link forming means 41 having The direction of rotation of the pair of left and right rotating shafts 43 and 43 is indicated by an arrow D2.

[0077] The discharge port 3b of the filling tube 3, the locus circle Q of the apex 42a of the pincher member 42, the rotation shaft 43, the adhesive application nozzle 22, the adhesive discharge start position IV, and the adhesive discharge stop position V are respectively the device. Same position as 1.

[0078] The filling casing moving means 44 has an arrow D1 around the rotary drive shaft 45 and the idler shaft 45a. A winding transmission 46, 46 having a pair of left and right chains or belts continuously circulating in a direction at a predetermined speed is provided. The pair of winding transmissions 46 and 46 sandwich the filling casing 7 (filling portion 7b) therebetween, and move the filling case 7 from the discharge end 3b to the rear (in the direction of arrow A) at a predetermined speed.

[0079] The pincher member 42 constricts the filling casing 7 moving at a predetermined speed at a cycle in which a filling having the same length as the filling corresponding to the interval E of the apparatus 1 is formed. The adhesive application nozzle 22 discharges the adhesive 21 at the same cycle as the apparatus 1 and forms an adhesive application portion 21A having a length K on the outer periphery 7A of the filled casing 7 at intervals E. Thus, similarly to the device 1, the twisted portion 7a to which the adhesive 21 is applied is formed.

[0080] As with the previous device 1, this device 40 can also be applied to the twisted portion 7a with the adhesive 21 being wound in the twisted portion 7a, or the outer periphery 7aa of the twisted portion 7a can be covered with the adhesive 21. The adhesive 21 can be applied to the twisted portion 7a. Furthermore, it is possible to produce a filling material in which an adhesive is applied only to the twisted portion 7a, or a filling material in which an adhesive is applied to both the twisted portion 7a and the filling portion 7b.

FIG. 18 and FIG. 19 show a modified example of the device 40 in which the adhesive application nozzle 22 is arranged closer to the opposite content discharge direction than the device 40 shown in FIG. 16 and FIG. The adhesive application nozzle 22 is arranged at a position above the casing 5 in which the contents are not yet filled, in a predetermined distance H direction (arrow B direction) from the discharge port 3b of the filling tube 3. In this example, while the adhesive is applied to the outer periphery 5A of the casing 5, the casing 5 coated with the adhesive is filled with the contents. In this manner, the adhesive is applied to the outer periphery 7A of the filled casing 7.

As described above, any of the above-described examples has the following operational effects.

After applying the adhesive 21 to the outer periphery 7A of the filled casing 7 having a diameter sufficiently larger than the diameter of the twisted portion 7a, the filled casing 7 where the adhesive 21 is applied is squeezed and twisted to twist the twisted portion 7a. Therefore, the twisted portion 7a to which the adhesive 21 is applied can be formed in the circumferential direction (arrow G direction) and the longitudinal direction (arrow L direction).

As a result, the formation of the twisted portion 7a can be achieved by simply applying the adhesive 21 from the adhesive application nozzle 22 to one place on the outer periphery 7A of the filling casing 7, resulting in a device having a simple structure. Since the adhesive 21 is applied to the outer periphery 7A of the filled casing 7 having a diameter sufficiently larger than the diameter of the twisted portion 7a, it is not necessary to precisely determine the target position of discharge from the adhesive application nozzle 22. As a result, the amount of rotational runout of the filled casing 7 can be increased, so that a high-speed coating operation can be performed.
